DaMoshe, as I wrote, “A chevrah which wants a kiddush club will choose a shul with a Rav who lets it go”.
Sure, in theory, if no shul would allow it, it wouldn’t exist. But l’maaseh, if every shul would ban it, another shul would open which allowed it.
I think we’re really in agreement here. We both find the behavior unacceptable, and feel that the Rav should put his foot down. I just want to add that we need a mehalach of how to deal with this unfortunate reality, and not be satisfied with only expressing our indignation.
